C, D, E

Explanation:

At a convergent (destructive) plate boundary. The denser oceanic tectonic plate is moving towards a less dense continental plate. Convection currents in the mantle move the plates together. The continental plate is thicker and higher. At the boundary between the two plates, the oceanic plate starts to slide under the lighter continental plate. The dramatic gap in height between the two plates is the oceanic trench.
